You have to walk carefully in the beginning of love. Running across fields into your lover's arms can only come later when you're sure they won't laugh if you trip.
Being careful is second nature to some, but others never seem to take care or worry about anything at all. Being careful does not mean that you can not enjoy life or take any risks at all, but your safety should always be a priority. There is such a thing as being too careful, to the point where you do not enjoy life and spend all of your time worrying about what might or might not happen. Take time to seize the day and take advantage of the opportunities that life offers.
